Rails 3 engines testing

Hi all,

I was wondering how you can test Rails 3 engines.

Looks like the rake test task is not available by default. So I added the following in my rake task

require 'rake/testtask'

Rake::TestTask.new do |test|   test.pattern = 'test/**/*_test.rb'   test.libs << 'test' end

In my test_helper.rb file, I added:

ENV["RAILS_ENV"] = "test"

require 'rubygems' require 'test/unit' require 'active_support'

But still no go. If I want to run the test, I get some error messages about a namespace I'm using (everything else is still running smoothly).

So how do you integrate the default rails testing framework from ActiveSupport into your Rails 3 Engines?

Thank you in advance
